suspected clot :/

hii so i recently was just on bed rest for a little while because i was pregnant and i assume that if i have a clot that's why it flared up. i recently had a medical abortion that lasted from 11pm on saturday to 3am on sunday. i noticed the change in my leg last night and called 111 as soon as i noticed and they did send me to a&e to get things checked. it's just behind my knee where the swelling is and they sent me home last night as they couldn't scan me but it didn't seem like anything major, it was less than one inch of swelling and could be nothing but they did tell me to get an appointment with my doctor to get a scan done. im currently waiting for a response from my doctors and im kind of worried that something could go wrong in that time but i also do know that i can just go back to a&e. i don't have any type of pain in my leg at all it just feels like ive pulled a muscle more than anything else so im not sure if it's anything bad, i can still walk fine and the weird feeling above the knee goes away whenever i've been walking for a normal amount of time. im only 18 and i feel like this is the last thing i need on my plate right now :/// any help would be appreciated thank you so much
